Description

Technical Field

[0001] The utility model belongs to the technical field of constant temperature devices, and in particular relates to a constant temperature device for stem cell culture. Background Art

[0002] Cell culture refers to a technology that allows cells to grow, reproduce and maintain their main structure and function under artificially created conditions similar to the in vivo environment (such as suitable temperature, pH, and certain nutrients). A constant temperature device is usually used to culture cells.

[0003] A Chinese patent with announcement number CN218321443U discloses a constant temperature culture device for stem cells, comprising a box body, the inner wall of which is fixedly installed with a partition, the box body is divided into a carrying chamber and a heating chamber by the partition, a plurality of groups of slide rails distributed in an array are fixedly installed in the carrying chamber, a carrying box is slidably installed on the top of each group of the slide rails, the tops of the plurality of carrying boxes are open, the plurality of the carrying boxes are slidably penetrated with the box body, and a through hole is opened on one side of the plurality of carrying boxes close to the carrying chamber.

[0004] The above technical solution can realize the multi-layer temperature control function by setting up multiple carrying cavities, which solves the problem that the incubator usually has only a single culture cavity, resulting in only a single batch of stem cells being cultured. However, during use, since there are many chambers set inside, a large space is required when transporting or not in use, resulting in a large space occupancy rate.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0010] Optionally, in order to improve the operability of expanding and closing the outer frame, the telescopic frame and the closed frame, the operating mechanism includes an extension plate fixedly connected to one side of the top frame, a lifting plate fixedly connected to the lower side of the extension plate, a fixed plate fixedly connected to the upper side of the bottom plate and slidingly matched with the inner wall of the lifting plate, two plug-in grooves opened on one side of the fixed plate, and a plug-in pin threadedly matched on one side of the lifting plate and matched with the two plug-in grooves.

[0011] Optionally, in order to improve the convenience of pulling out the L-shaped display boards, an operating groove is provided on one side of each of the multiple L-shaped display boards.

[0012] Optionally, in order to increase the stability of the L-shaped placement board when being pulled out, limiting grooves are provided on the lower sides of the outer frame, the telescopic frame and the inner wall of the closed frame, and the inner wall of the limiting groove is slidably matched with a limiting block fixedly connected to the L-shaped placement board.

[0013] Optionally, in order to improve the convenience of moving the operating handle up and down, an operating handle is fixedly connected to one side of the extension plate.

[0027] See also Figure 1-4 As shown, in this embodiment, a constant temperature device for stem cell culture is provided, comprising a bottom plate 1, an outer frame 2 is fixedly connected to the upper side of the bottom plate 1, a telescopic frame 3 is slidably matched with the inner wall of the outer frame 2, a closed frame 4 is slidably matched with the inner wall of the telescopic frame 3, a draw-out opening 5 is opened on one side of the outer frame 2, the telescopic frame 3 and the closed frame 4, and an L-shaped placement plate 12 is slidably matched with the inner wall of the draw-out opening 5;

[0028] A hollow plate 6 is installed on the upper side of the bottom plate 1, and a sliding frame 7 is slidably matched with the inner wall of the hollow plate 6, and a top frame 8 is slidably matched with the inner wall of the sliding frame 7. A connecting valve 9 is installed between the hollow plate 6 and the sliding frame 7, and between the sliding frame 7 and the outer frame 2, the telescopic frame 3 and the closed frame 4. A heating rod 10 is installed on the lower side of the inner wall of the hollow plate 6, and an operating mechanism 11 is installed on one side of the top frame 8.

[0029] One aspect of the application of this embodiment is as follows: when in use, heat is generated by the heating rod 10 and transmitted to the outer frame 2, the telescopic frame 3, and the closed frame 4 through the corresponding connecting valves 9, and then the L-shaped placement plates 12 are respectively pulled out, and the vessels to be cultured are placed on the upper side of the inner wall of the L-shaped placement plate 12, and then the limiting groove 14 seals the withdrawal opening 5 to achieve heating and constant temperature;

[0030] During placement or transportation, the lifting plate 112 is moved downward by operating the plug pin 115 in the operating mechanism 11. During the movement, the top frame 8 is hidden in the sliding frame 7, the sliding frame 7 is hidden in the hollow plate 6, and similarly, the closed frame 4 is hidden in the telescopic frame 3, the telescopic frame 3 is hidden in the outer frame 2, thereby reducing the overall height, reducing its space occupancy rate, and improving the convenience during transportation.

[0031] The operating mechanism 11 of this embodiment includes an extension plate 111 fixedly connected to one side of the top frame 8, a lifting plate 112 fixedly connected to the lower side of the extension plate 111, a fixing plate 113 fixedly connected to the upper side of the bottom plate 1 and slidingly matched with the inner wall of the lifting plate 112, two plug-in grooves 114 provided on one side of the fixing plate 113, and a plug-in pin 115 threadedly matched with one side of the lifting plate 112 and matched with the two plug-in grooves 114;
